The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:1204 advisory.

    The java-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Java     Software Development Kit.

    Security Fix(es):

    * An untrusted library search path flaw was found in the JCE component of OpenJDK. A local attacker could     possibly use this flaw to cause a Java application using JCE to load an attacker-controlled library and     hence escalate their privileges. (CVE-2017-3511)

    * It was found that the JAXP component of OpenJDK failed to correctly enforce parse tree size limits when     parsing XML document. An attacker able to make a Java application parse a specially crafted XML document     could use this flaw to make it consume an excessive amount of CPU and memory. (CVE-2017-3526)

    * It was discovered that the HTTP client implementation in the Networking component of OpenJDK could cache     and re-use an NTLM authenticated connection in a different security context. A remote attacker could     possibly use this flaw to make a Java application perform HTTP requests authenticated with credentials of     a different user. (CVE-2017-3509)

    Note: This update adds support for the jdk.ntlm.cache system property which, when set to false, prevents     caching of NTLM connections and authentications and hence prevents this issue. However, caching remains     enabled by default.

    * It was discovered that the Security component of OpenJDK did not allow users to restrict the set of     algorithms allowed for Jar integrity verification. This flaw could allow an attacker to modify content of     the Jar file that used weak signing key or hash algorithm. (CVE-2017-3539)

    Note: This updates extends the fix for CVE-2016-5542 released as part of the RHSA-2016:2658 erratum to no     longer allow the MD5 hash algorithm during the Jar integrity verification by adding it to the     jdk.jar.disabledAlgorithms security property.

    * Newline injection flaws were discovered in FTP and SMTP client implementations in the Networking     component in OpenJDK. A remote attacker could possibly use these flaws to manipulate FTP or SMTP     connections established by a Java application. (CVE-2017-3533, CVE-2017-3544)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
